The oppositely moving pair of dies are connected to a suitable movingframework G mounted on rods Gr sliding through ways Gr carried on thestationary frame of the machine at each side thereof. The intermittentmove ment of the airs of dies "toward each other is accomplished in theinstance illustrated by the links H, the bell cranks H the pitman rod Hand the cam H mounted on the shaft H and actuated from the main powerThe adjustment and time is such, as indicated in the drawing, that theloosely headed can bodies are fed by the feed chains intermittently stepby step until the first one reaches the position of the, first pair ofholding and heating dies. Here the can body stops momentarily and thepair of heating dies close upon it in opposite directions, forcing theheads or ends firmly upon the'body and holding them momentarily there inthe heated dies, after which said dies separate away from the can bodiesand from the holding plates E leaving the headed can with its heatedheads free in the feed chains. The feed chains now move another spacebringing the can. into position opposite the second pair of dies whichmay preferably be a closer approximation to the final shape and the nextsucceeding can into position opposite the first pair of dies when theoperation of compressing, heating and releasing is repeated. Thisoperation is thus continuously repeated until all of the cans are fedthrough the machine and discharged completely headed at the other end ofthe machine with the heads fitted and shrunk smoothly in place. By thusoperating several times successively by different pans of dies upon thesame can, the total time of the heating and drying action is multiplied,without cdrrespondingly multiplying the length of time required forfeeding the cans through the machine. And when the pairs of dies aremade successively more nearly conformed to'the final form required, theyoperate gradually to shape the heads to such final form. The intervalsof time during which the body and heads are released from the diesserves to permit .the free escape of vapor from the moist heads and thusto facilitate the ultimate and complete drying and settin g of thematerial.
